It may not be as exciting as the announcement of a new flagship product, but Onkyo's new home theater systems are surprisingly impressive.

Both the 7.1 channel HT-S5400 and the 5.1 channel HT-S3400 feature 3D
compatibility, Dolby TrueHD and DTS-HD Master Audio decoding as well as
an audio return channel. They boast PLL jitter-cleaning circuitry,
Burr-Brown DACs and a new Advanced Music Optimizer that helps to restore
some life to those compressed audio files.

The 5400 offers ProLogic IIz audio processing technology for those that
want height channels, a USB port allowing for direct connection to an
iPod or iPhone, a powered subwoofer and Audyssey 2EQ which adjusts the
sound to fit your listening area.

Onkyo's HT-S3400 ditches the USB port and subwoofer pre-out , but still includes a down-firing subwoofer and five speakers.

You'll be able to pick up both systems in April at $599 for the 5400 and $379 for the 3400.
